I've uploaded the finished levels to my google drive, you can access and play them at your leisure here:

Any feedback is great! Is the difficulty right? Did I miss a texture somewhere? Thanks!
My other major issue is the "Corkskrew" (level 4) mission. The engine does not seem to like it, and I can't figure out why. It seems somehow linked to the number of doors/walls, but that makes no sense cuz I've made other levels with far more objects/walls/triggers. Is it possible a wall isn't configured properly? Or it just doesn't like one of the doors? If so I would love to find out which one. I like how that level turned out and would hate to have to scrap important parts of it. The level is in the folder above.
Also, all the hostages still show up tiny, and I have no clue how to fix it.

No idea of the timeline for the rest of the mod. I've got 3 other levels with some substantial work done, so that leaves me 2 or so more to make from scratch. I also plan to do a once over everything and work on making the lighting more dynamic. I would say early next year I'll try to share it.
Thanks to everyone that's helped me thus far! Modding like this is still pretty new to me, so I appreciate any advice I get.
